TL;DR: In this article, a system and method for enabling real-time off-site video image storage is described, where an offsite storage site is coupled to camera servers at client sites via a private network.
Abstract: A system and method for enabling real-time off-site video image storage is disclosed. An off-site storage site is coupled to camera servers at client sites via a private network. Each camera server is further coupled to one or more surveillance cameras. Video images captured by cameras located at the client sites are forwarded to an off-site server via a camera server. Video images received by the off-site server are produced for live viewing and/or archived in an image database. Users can retrieve live or archived video images through a client workstation that communicates with the off-site server over the public Internet. Retrieval of video images is based on a web-browser interface. Live viewing of video images is supplemented by real-time camera control functions that alter the pan-tilt-zoom (PTZ) position of the camera producing the live images. Commands for controlling the PTZ camera are encoded by the client workstation and transmitted to the off-site server. The off-site server converts the camera control codes into control strings that are recognizable by the particular camera.

Abstract: A programmable digital camera requiring a programming password to be entered to access the camera's programmability. The camera further includes programming so as to allow the camera to be operated only for a specified time interval, after which the camera becomes inoperable until the programming password is again entered and the camera is programmed to operate for another interval of time. An alternate embodiment of the invention includes a programmable digital camera as above described wherein the camera is programmed to only capture a set number of images, at which point the programming password must again be entered and the camera reset for another quantity of images. A further alternate embodiment includes a camera system with a separate transmitter for radiating a signal designed to cover a designated area, the signal being modulated with a camera operational code. The camera is equipped with a corresponding receiver and demodulator to receive the operational code. The camera is programmed to check for the operational code periodically, and if the code is not received, the camera automatically shuts down, thereby limiting operation of the camera to the designated area. A still further embodiment includes a camera with a built-in apparatus for acquiring measured biometric data of a potential user, and comparing it with corresponding biometric signature data entered in the camera, and allowing camera operation only if there is a match.

TL;DR: In this paper, a system is presented that creates vision-based, three-dimensional control of a multiple-degree-of-freedom dexterous robot, without special calibration of the vision system, the robot, or any of the constituent parts of the system, and that allows highlevel human supervision or direction of the robot.
Abstract: A system is presented that creates vision-based, three-dimensional control of a multiple-degree-of-freedom dexterous robot, without special calibration of the vision system, the robot, or any of the constituent parts of the system, and that allows high-level human supervision or direction of the robot. The human operator uses a graphical user interface (GUI) to point and click on an image of the surface of the object with which the robot is to interact. Directed at this surface is the stationary selection camera, which provides the image for the GUI, and at least one other camera. A laser pointer is panned and tilted so as to create, in each participating camera space, targets associated with surface junctures that the user has selected in the selection camera. Camera-space manipulation is used to control the internal degrees of freedom of the robot such that selected points on the robot end member move relative to selected surface points in a way that is consistent with the desired robot operation. As per the requirement of camera-space manipulation, the end member must have features, or “cues”, with known location relative to the controlled end-member points, that can be located in the images or camera spaces of participant cameras. The system is extended to simultaneously control tool orientation relative to the surface normal and/or relative to user-selected directions tangent to the surface. The system is extended in various ways to allow for additional versatility of application.

TL;DR: This work presents a novel approach to controlling a virtual 3D camera with a 2D mouse or stylus input device that is based on gestural interaction and requires only a single-button stylus or mouse to directly invoke specific camera operations within a single 3D view.
Abstract: We present a novel approach to controlling a virtual 3D camera with a 2D mouse or stylus input device that is based on gestural interaction. Our approach to 3D camera manipulation, UniCam, requires only a single-button stylus or mouse to directly invoke specific camera operations within a single 3D view. No 2D widgets or keyboard modifiers are necessary. By gesturally invoking all camera functionality, UniCam reduces the modal nature of typical desktop 3D graphics applications, since remaining mouse or stylus buttons can be used for other application functionality. In addition, the particular choice and refinement of UniCam controls efficiently enables a wide range of camera manipulation tasks, including translation in three-dimensions, orbiting about a point, animated focusing on an object surface, animated navigation around an object, zooming in upon a region, and saving and restoring viewpoints. UniCam’s efficiency derives primarily from improved transitions between techniques and to a lesser degree from adaptations of existing techniques. Although we have conducted no formal user evaluations, UniCam is the result of years of iterative development with approximately one hundred users. During this time more conventional modifier key and menu-based implementations were implemented and either refined or rejected. Informally, users appear to require a few hours of training to become proficient with UniCam controls, but then typically choose them almost exclusively even when widget-based controls, such as those provided by an Inventor viewer, are simultaneously available.

TL;DR: A dynamic sensor-planning system that is capable of planning the locations and settings of vision sensors for use in an environment containing objects moving in known ways is presented.
Abstract: This paper presents a dynamic sensor-planning system that is capable of planning the locations and settings of vision sensors for use in an environment containing objects moving in known ways. The key component of this research is the computation of the camera position, orientation, and optical settings to be used over a time interval. A new algorithm is presented for viewpoint computation which ensures that the feature-detectability constraints of focus, resolution, field of view, and visibility are satisfied. A five-degree-of-freedom Cartesian robot carrying a CCD camera in a hand/eye configuration and surrounding the work cell of a Puma 560 robot was constructed for performing sensor-planning experiments. The results of these experiments, demonstrating the use of this system in a robot work cell, are presented.

TL;DR: The purpose of this method is to choose a trajectory for a virtual camera, allowing the user to have a good knowledge of the scene at the end of a minimal flying over, by combining good view, smooth camera movement and distance from the starting point based heuristics.
Abstract: A method for visual understanding of a scene by efficient automatic movement of a camera is presented in this paper. The purpose of this method is to choose a trajectory for a virtual camera, allowing the user to have a good knowledge of the scene at the end of a minimal flying over. The method is based on techniques for computing a good point of view, used together with various heuristics, in order to have smooth movement of the camera and to avoid fast returns to the starting point, due to local maxima. So, starting from a good view point, the virtual camera moves on the surface of a sphere surrounding the scene, combining good view, smooth camera movement and distance from the starting point based heuristics.

TL;DR: In this paper, a system and method for selectively providing display data to a display device dependent upon an optically detected proximity of a user's face to a camera is described, where the processing system receives the image signals and analyzes the first and second images to determine the proximity of the user face to the camera.
Abstract: A system and method are described for selectively providing display data to a display device dependent upon an optically detected proximity of a user's face to a camera. One embodiment of a computer system includes the camera, the display device, and a processing system. The camera produces image signals representing a first image and a second image of the user's face, wherein the first image precedes the second image in time. The processing system receives the image signals and analyzes the first and second images to determine the proximity of the user's face to the camera. More specifically, the processing system compares the first and second images to determine the proximity of the user's face to the camera in the second image relative to the proximity of the user's face in the first image. The processing system provides the display data to the display device dependent upon the proximity of the user's face to the camera. In order to determine the proximity of the user's face to the camera, the processing system may compare: (i) a size of the user's face in the first and second images, and/or (ii) a distance between selected facial features of the user in the first and second images. The processing system may provide more of the display data to the display device when the user's face is closer to the camera, and may provide less of the display data to the display device when the user's face is farther from the camera.

TL;DR: An experimental system that can detect and track multiple moving objects in real-time using a PAL camera system that serves the initial step of the panoramic virtual stereo (PVS) vision approach.
Abstract: Flexible, reconfigurable vision systems can provide the richest sensing modality for sophisticated multiple robot platforms. We propose a cooperative and adaptive approach to vision applied to the problem of finding and protecting humans by a robot team in such emergent circumstances, for example, during a fire in an office building. A panoramic camera system plays an important role in this approach. This report presents the recent progress on the development of vision algorithms based on a panoramic annular lens (PAL) camera system. First, we give a brief survey of existing panoramic camera systems, with an emphasis on geometrical properties of capturing panoramic images from a single-viewpoint. Second, a mathematical model of the panoramic annular lens (PAL) camera that we use is built, and then several issues about camera calibration and image un- warping are addressed. An empirical method is given to roughly ''calibrate" the PAL camera system. Next, a panoramic virtual stereo (PVS) vision approach is proposed, and the problems of self-calibration and real-time 3D estimation are discussed. Finally, we present an experimental system that can detect and track multiple moving objects in real-time using a PAL camera system. The panoramic vision algorithm for moving object tracking also serves the initial step of the PVS approach.
